- whims. (orsi-2c) 'I'his invention relates to drlers of the general type employed in beauty parlors and barber shops for dryingl the scalp and hair after shampooing, washing, or other treatments have been given, and the main object is to provide an efficient,

practical, and highly novel constructionof'mech-V anism ordrier unit for that purpose. Other more detailed and specific. objects will be disclosed in the course of the following specification, reference being had tothe accompanying drawing, wherein: f A,

Fig.- 1 is an enlarged "sectional elevation taken diametri'cally throughv the drier unit.

Fig'. 2 is a. cross sectional view as seen substantially on the irregular line 2--2 in Fig. 1.

The structure of the drier unit includes a dome shaped housing or outer shell 8 which carries the entire drying mechanism, and is in turn supported on a portable standard or other support,

the details of which formv no part of the present invention. Spa/ced within the housing 8 are two inner shell-like members. 9 and I0, the latter of which'may bereferred to asa masi: or inner fdome, and it is the enclosure'deilned by this dome that receives or is'plalced` over 'the head 'having -the hair to be dried. 1 Thelower'portions of the shell-like members 8, 9, and Ill, are concentrically spaced with respect to'each other'lto provide an inner annular chamber'II and any outer annularchamber I2,and the lower ends of these chambers are closed by an integral flange portion I3 of the dome III which extends outwardly lasv shown in Fig. .6 to receive the lower.end edges of the members 8 and 9.

The inner annular chamber II terminates-above the dome I0 in a relatively large central chamber I4, in which operates a fan or blower I5. The

, fan I 5A is of the propeller or radial thrust type, and when operatedfunctlons to create a' down draft of air about the domejlli and into the interior, thereof through a`series of spaced holes I6. The air thus passingthrough theholes or portsv le to the mteri'orof the mask In is .not

50 way reenter the annularA chamber II. Thus it rvdischarged fromthe unit, however, but isdlverted back through lopenings Il which are dewill be Vseen that the air current created-by the 'fan' l5 win pass into the interior of the dome lo at spaced points about the head having the hair the openings I8 at other spaced points, and from thence passes up through the annular chamber I2, all as indicated by the direction arrows. A At its upper end the intermediate shell 9 is rigidly secured to an annular cast rim I9 which 5 in turn is provided with circumferentially spaced radial lugs or spokes 20 that fit snugly within the housing 8 and are rigidly secured therein as by screws 2I. These screwsv not only secure the rim I9, but also operate through the rim to re- 10 leasably securev the entire drying mechanism within the housing 8, and consequently when these screws are'removed the entire drier structure can be bodily removed downwardly out of the housing 8. 15 An air deflecting'cup 22 extends axially down within the rim I9 and into the chamber I 4. This cup 22 has a wide ange 23 at its upper end which is spaced above the rim or ring I9, and is rigidly secured in this spaced relationship by 2o spacer lugs-24 and screws 25. Spaced within the cupv22 and tapering downwardly to conform 'with -the contour thereof, is an upwardly ex.

tending sleeve 26 which is rigidly secured to the cupfas at 21, and is suiliciently spaced from the 25 cu'p to provide an annular passageway 28 for the circulation 'of a secondary air current, as

will presently be described.

Mounted within the sleeve 26 is the operating l motor 29 having a spindle 30 at its lower end for 30 l supporting the main 4fan I5, and at its upper end the motor shaft has a secondary fan 3l which operates within the upper end of the sleeve 26.

V-The purposeof the f an 3I is to draw relatively cool air down through openings 32 in the upper end of 35 the housing ii,`and move it downwardly within the sleeve 26 to cool the motor 29. After cooling the motor the secondary air current passes down into the'cup 22, up through the annular space 28, and

over the cup ange 23 to a restricted 'annular lliY .passageway 33 between the flange 24 and the housing 8., At this point thel secondary air current which has becomev partially heated by the motor 29 is taken'up land absorbed by the main air current which is passing up through the annular chamber I2 inwardly over the ring I9and thence downwardly into the chamber I4, to be recirculated through the openings I6 and Il as has valready been described.

In order to raise the Vtemperature of the primary air current I provide a pair'of. heating elements in the form of circular coils 34 which are suitably mounted and insulated, and which are yso arranged that they will intersect the air current passing inwardly under the ilange 24 and 56 downwardly about the cup 22. A conveniently arranged switch 35 is connected with the heating unit Il and is also preferably connected with the motor 29 so that one switch may be employed to control both electric members, and thus also insure energization of the heating elements whenever the motor is put in operation.

From the foregoing it will readily be seen that when the switch 35 is closed the motor 29 will immediately put the fans I5 and 3i in motion, whereupon the primary and secondary air currents will be created, and as soon as the heating elements 3l begin to function the primary air current will be heated thereby to thus increase the drying efiiciency of the structure.

It will be understood that suitable modifications may be made in the structure as disclosed, provided such modifications come within the spirit and scope of the appended claims. Having now therefore fully illustrated and described my invention, what I claim to be new and desire to protect by Letters Patent is:

1. A drier of the character described comprising an outer housing, an inner hood having inlet and outlet openings, a fan for circulating air through the openings, a shell member disposed intermedlate said housing and hood to form annular chambers therebetween, said outlet openings being defined by tubular members connecting said hood and shell and extending through the inner of said annular chambers to establish independent communication between the hood and the outer of said chambers.

2. In a drier the combination comprising a housing having an apertured hood mounted in one end thereof, a partitioning shell extending from adjacent the base of the housing with its upper end edge remote from the hood, a cup member positioned in the upper end of the shell and having a flange portion spaced therefrom to provide an annular restricted passageway between such shell end edge and the cap flange portion, and a motor and fan carried by the cup for producing a positive circulation of air inwardly through said restricted opening and thence downwardly to the apertured hood.

3. In a drier the combination comprising a housing having an apertured hood mounted in one end thereof, a partitioning shell extending from adjacent the base of the housing with its upper end edge remote from the hood, .a cup member positioned in the upper end of the shell and having a flange portion spaced therefrom to provide an annular restricted passageway between such shell end edge and the cup flange portion, means for producing an air circulation inwardly through said restricted opening and downwardly to the apertured hood, and an electric heating element arranged between the cup member and the adjacent end of the partitioning shell to heat the air circulated through therebetween.

4. A drier of the character described comprising a housing having a hood in one end thereof provided with inlet and outlet openings, a partitioning shell defining inner and outer chambers respectively communicating with the hood, a flanged cup member secured to the upper end of the partitioning shell and spaced therefrom to provide a connecting passageway as between said chambers, and a power driven fan in the inner chamber.

5. A drier of the character described comprising a housing having a hood in one end thereof provided with inlet and outlet openings, a partitioning shell defining inner and outer chambers respectively communicating with the hood, a flanged cup member secured to the upper end of the partitioning shell and spaced therefrom to provide a connecting passageway as between said chambers, and spaced from the housing to provide a second restricted passageway, a motor arranged in the cup member to drive a main fan disposed thereunder, and a second fan driven by and for cooling the motor, said second fan being disposed above the cup member and adapted to circulate air through said second restricted passageway.A

6. A drier of the character described comprising a housing having a hood in one end thereof provided with inlet and outlet openings, a partitioning shell defining inner and outer chambers respectively communicating with the hood, a flanged cup member secured to the upper end of the partitioning shell and spaced therefrom to provide a connecting passageway as between said chambers, and spaced from the housing to provide a second restricted passageway, a motor arranged in the cup member to drive a main fan disposed thereunder, a sleeve about the motor, and a second fan operated by the motor .and arranged to circulate air through the sleeve.

7. A drier of the character described comprising a housing having a hood in one end thereof provided with inlet and outlet openings, a partitioning shell defining inner and outer chambers respectively communicating with the hood, .a fianged cup member secured to the upper end of the. partitioning shell and spaced therefrom to provide a connecting passageway as between said chambers, and spaced from the housing to prof ranged to circulate air through the sleeve, said sleeve being projected down into the cup member but spaced therefrom to provide an annular air passageway.
